'vTo all whom 'it may. concern? A' y Beit kn'own that I, DANIEL M. KENYON, a citizen of the nited States, residing `at Bradford, inthe county` ,of McKean and State of Pennsylvania," have invented A new and useful Improvements in Implements for Coup?4 ling 1.ipes, of which the following is a specification.

My invention relates to a toolor implement for in-,v'

v serting sectionsof pipe into couplings; and the object of my invention'is to provide a practical means for installing a pipe system withoutinjilring the packing.

' of another pipe member7 the said packing ordinarily I l5 being an annular ring of compressible material whose -interior diameter is smaller than that ofthe pipe to be inserted in the coupling.

invention' further consists in the various details of construction and improvements'hereinafter specific- Refe'rence is hereby made to the `accompanying drawingin which similar .numeralsof designation ref'er to.

similar parts throughout the several views. j

Figure l is a longitudinal section of the coupling, pipe and packing, showing my improved tool or implement used for applying the coupling. Fig.'2 .is a longitudinal section oi the coupling, packing and pipe, showing the position of my improved inserting implement or strips after the coupling has been applied and before the said strips have been withdrawn, and also showing theposition of the collar used for effecting such withdrawal.. Fig. 3 is an end elevation of the coupling and the inserting implementor strips shown-in Fig. 1.C Fig. 4 is a perspective view of one of the inserting strips. Fig.

5 is an end elevation ofthe coupling, showing a modifiis a plan viewof the coupling, packing, pipe, iinplement and collar shown in Fig. 2. Fig. 8 is an end elevation, looking. in the direction of the arrow, of the collar used for removing the inserting implement or strips from the coupling and pipe.

Referring to the drawings,- 3'indicatesone pipe member, shown as a coupling of metal or other suitable ma terial having on the interior thereof annular recessesllO adapted to receive and retain rings of compressible material. The section 5 or the section 6 constitutes the other pipe member to be joined to the member 3. v The packing riiig 4 is preferably so formed that before being compressed it is sufciently thicker than the width of the space between the opposing walls of the members to be coupled, to prevent the assembling of such meml specificati-onor' Letters Patent.

.bers solely by the insertion-of one member within the othen The saidv sections ofpipe 5I and 6 are usually of l. i

' Iiron or steel but may be of anyother suitable material. f

Iny Fig. 1V is shown one section of pipe 5 already in' i sertedin the coupling, theother end of the'coupling' being shown with the strips 7 and 7b in position for the insertion of the othersection 'of pipe 6. Preferably each of said strips 7 and 7bk bears thereon the spring 8 v which is attached to it in any .approved manner;` the object of said spring 8 being to grip the edge of the coupp ling and to retain the strips-7 and 7l in positionwhile the pipe 6 is being inserted. f The spring 8 may also be stamped or pressed out ofthebody of the strips. V, Itis,

however, notessential to use the said spring at all as it isl obvious that the strips may be held in place by the hand or other means. Each of said strips 7n and 7l is a thin strip of metal or other suitable material which'is curvilinear incross section and is adapted to be readily introduced in the coupling in sch a manner as to` be easily removed afterl the section of pipe has been inserted, there being .sl'uiilcienti space between the exterior surface of said pipe or conduit and the interior surface of saidy couplingto permit this operation.l The strips 7L areiirst inserted into the coupling and afterwards the strips 7b so that the edges of the latter overlap the edges of the former as shown in Fig. 3. Preferably each of Asaid strips 7a and 7b tapers-toward one end thereof, a small portion of the other end being turned up at right angles thereto for the purpose o engaging with the collar shown in Figs'. 2, 7 and 8. It is obvious that the said strips may be inserted in various ways into the coupling. serted edge to edge so that when the pipe is installed In Fig. 5, I have shown ,them inthey completely surround the same and` at the same time press back the packing. In Fig. 6, I have shown the said strips overlapping each other at their adjacent Y I have found in practice that it isdesirable, though not essential, to have the edges of the strips overlap,

so that by no accident could the strips be spread so as to allow the packing when compressed to protrude between their edges and be sheared 0H by the edge of the pipe. In such case grooves would be formed on the inner surface of the packing and would not afford as tight a joint as 'a perfectly smooth surface. Y

I alsofound it desirable to construct the strips 7 and 7b of'different lengths in order thatthe same may be more readily removed from th`e coupling-'by the collar The said i shown in Fig. 8 or other well known devices.

ioo

collar .is formed by two semi-circular sections 15 and in the manner shown in Figs. 2 and 7. -By moving it to the right, it first engages thel turned up portion of cach of the strips .7, and these aro moved in the saine direction until the said collar engages the turned up portions of cach of tho strips 7, when all of the strips then start together. l find it advisable to use this method ot removal as it is obvious that the strips may be started vmore easily thereby, and thc strain of 'withdra-wal more easily overcome, than when they are all moved at the same time.

While I have shown the stripsin two lengths, I do not desire to be limited to the use of but two sizes of the strips, assit is apparent that I could use varying lengths of 'said strips with good results.

It is also'apparent that it is not essential to have the strips curvilinear in cross section,- as fiat strips or strips of variousliorms may be used to good advantage. Gren-y erally, any form oi strip would serv the purpose of my invention, provided that a plurality oi the strips when inserted in the coupling would be capable of compressing the packing. l
